Si873x Data Sheet
Low Input Current LED Emulator, Logic Output Isolators
The Si873x isolators are pin-compatible, single-channel, drop-in replacements for pop-
ular optocouplers with data rates up to 15 Mbps. These devices isolate high-speed digi-
tal signals and offer performance, reliability, and flexibility advantages not available
with optocoupler solutions. The Si873x series is based on Silicon Labs' proprietary
CMOS isolation technology for low-power and high-speed operation and are resistant
to the wear-out effects found in optocouplers that degrade performance with increasing
temperature, forward current, and device age. As a result, the Si873x series offer lon-
ger service life and dramatically higher reliability compared to optocouplers. Ordering
options include logic output with and without output enable options.
